@fuigb – the 12/3 is for the outlet to the saw itself. According to the chart above the wire at HD, it’s good for a 20 amp load. Not wanting to trust that alone, I checked other sources on the interwebs it seems fine too. As for whatever’s in the wall between the breaker and the outlet? Dunno, but I’m sure it meets whatever’s called for in the NEC – my electrician is a good guy.

@thedude50 – I thought long and hard about doing it myself. I’ve replaced an arc fault breaker in there that went bad before, so in theory I know my way around the panel, but that’s the problem – in theory. My background is in structural / mechanical engineering and there’s just some sort of mysticism about electricity that puts it out of my comfort zone. Spring, mass, damper? Makes sense. Capactitor, resistor, inductor? Que?

@jjmill1980 – Just checked continuity
At the wall plug, switch on: – Hot-neutral: yes – Hot-ground: no – Neutral-ground: no
At the wall plug, switch off: all no
At the motor, before the switch: – HN: yes – HG: no – NG: no
As I said earlier, I’m no electrician / electrical engineer, but it seems right to me.
